Definitions

  • each spray device with a clinometer the clinometer readings being transmitted to a point above the surface of the water and the composite of .these received clinometer readings permitting control of the trenching process so as to avoid that undesirable curvature.
  • the apparatus for carrying out the method according to the invention preferably comprises a number of spraying devices, arranged across the pipeline in a straddling manner, which are coupled together and provided with clinometers.
  • a train of spraying devices can be moved over the pipeline synchronously with the entrenching of the pipeline, so that synchronously with the entrenching process'the form of the pipeline can becontrolled as well. It is possible to automate the entire entrenching process, the speed of the train of spraying devices with clinometers depending on the permissible slope and the depth at which the pipeline is sunk into the soil-
  • the spraying devices may consist of uniformly spaced spray nozzles provided with the clinometer.
  • the drawing shows the entrenching of a pipeline 1 into the bottom 2.
  • four spraying devices 3 On the pipeline are arranged four spraying devices 3 in such a way that they straddle said pipeline, each of the spraying devices being provided with spray nozzles 4 and 5 respectively.
  • the devices are connected with one another by means of resilient connecting elements 7. With the aid of a pulling member 8, which is connected to means not shown, the train of devices 3 can be moved along the pipeline.
  • the spray nozzles 4 and 5 are connected with water pipes not shown, which extend from a vessel floating on the water with pumping setting and control means, for instance, which vessel can also receive the measurements of the clinometers 6 through cables not shown. From the data provided by the clinometers, the local slope of the pipeline and thus the radius of curvature can be controlled and, if the pipeline has to be entrenched with the aid of spray nozzles, adjustments can be made by controlling the spray nozzles, if desired.
  • the entire apparatus is preferably adapted to be moved in the length of the pipeline.
  • a method for determining the position of a pipeline or the like during the laying and/or entrenching of a pipeline comprising disposing a series of regularly spaced clinometers along the length of a pipeline, transmitting signals from said clinometers to a centrally disposed receiving zone thereby to provide data characteristic of the shape of the pipeline along said series of clinometers, entrenching the pipeline by means of spray devices spaced along the pipeline, moving said spray devices-along'the pipeline, and controlling the movement of said spray devices in dependency on said signals.
  • Apparatus for determining the position of a pipeline or the like during the laying and/or entrenching of said pipeline comprising a plurality of clinometers, means supporting said clinometers adjacent the pipeline in equally spaced relation in a series along said pipeline, means for moving said series of clinometers lengthwise along the pipeline while maintaining said equally spaced relation, and spray devices for entrenching said pipeline, said spray devices being spaced along said pipeline and articulately interconnected, said clinometers being connected to said spray devices for movement with said spray devices along said pipeline.
  • each said spray device comprising a framework having a plurality of spray nozzles thereon spaced apart lengthwise of the pipeline, and a said clinometer carried by said framework.
